<p>The process comprises the mixing of a water-based oxidant product having an oxygen proportion higher than 14 % and comprised of an aqueous solution which is saturated with oxidant salts, suspended oxidant particles and thickening agents, with a combustible and a gas in a mixer, to obtain the formation of an intimate mixture of the oxidant product and the fuel and the formation of a suspension or emulsion of gas in the mixture. The density of the final explosive product may vary as a function of the gas flow rate and is controlled before the explosive is introduced into the hole. The plant is comprised of a tank (1) containing the oxidant product, a combustible tank (11), a gas reservoir (10), a mixer (5), a pump (3), a fuel dosing device (12) with a flow rate meter (13) and a gas flow rate regulator (8) and, optionally, a tank (2) containing a stabilizer for the gas bubbles, a dosing pump (4) and a flow meter (7).</p> |
